2018 Mercedes Sprinter - tank capacity
Depending on the version, the 2018 Sprinter has a 71-litre tank or an enlarged version with 93 litres. The larger tank reduces the number of refuelling stops and increases the range, especially for long-distance journeys or commercial use.
2018 Mercedes Sprinter - Location of the fuel pump relay
The relay for the fuel pump in the 2018 Sprinter is located in the main fuse and relay box, usually under the dashboard on the driver's side or in the engine compartment. A fault in the relay causes the pump to fail, resulting in starting problems or engine misfires. A simple check with a multimeter can help to test the component. If necessary, it should be replaced to ensure a proper fuel supply.
Detecting a fuel leak in the Mercedes Sprinter III
To detect a fuel leak in the Sprinter III, check hoses, connections and the tank for damage or leaks. Typical indications are the smell of fuel, visible drips or increased consumption. A clean cloth makes it easier to localise damp spots. A quick repair prevents further damage and increases safety.
Tips for maintaining the fuel system
- Change the fuel filter every 30,000 km and make sure you use high-quality diesel to reduce contamination. - Inspect the lines regularly for cracks and check that the connections are tight. - In colder regions, additives are helpful to prevent the diesel from freezing and improve engine performance.
